APPARATUS Fon PREVENTING INcnUsmAtrIoN 0F WATER coins.

Application led March 11, 1926. l Serial No. *94,020,`

This invention appertains to water heaters lengthening the life thereof andthe prevention of the gradual" closing of the coil throughthe said adhesion of foreign matter thereto. y Y

It is generally known that the life* or period of useful service vofw'ater heating-'de- -vices in common use does not `depend materially upon the vdurability of thematerial from which they are made,yhut depends prif marily upon and is limited by the time in which minute particles, which separate from the water While the same is being' heated, close the device so that the Water cannot flow through it. The minute particles when once attached adhere very firmly to the interior of the coil until the walls thereof become thickened by such particles, which finally entirely close the device so that the water cannot flow through it, which results with the coil breaking, sometimes withV violent destructive eX- plosions. n i

The length of time in whichv a common water heating device will give eflicient service ranges from a few months to a few years, depending upon the quantity of water heated, the interior diameter or size of the device and the character of the water used, but

in every case the efficiency ofthe heating de-KVV vice constantly kdiminishes vin proportion as the adhesion attaches to and thickens its walls. yThe thickening of the walls commonly called liining up. and when the ad# hesionsare lonce attached, there is no prac#r tical way of `removing thesame.

It is therefore a prime object ofthe invention to provide a novel method of preventing n f the attaching of 'such adhesion o any.V sedi;

' ment from the water on the walls ofthe coils,

` sediment.

the method including novel means for ciifcuk lating with the water through the coilv for constantly keeping the walls clear from all Another object of the invention is the pro-k vision of a novel method for preventing the liming up of water coils .embodying the use of a non-corrodible ball mounted directly within the coil for continuous'circulation through thecoil with the water being heated:

A 'further object of the invention is the provision of novel means for preventing the adhesion of particles to the inside ofja water coil which includes means for reamingout thejin'terior of the coil to insure a smooth bore therethrough and the placing of a noncprro'dible ball of a slightly less diameter than'the bore of the coil therein for continuous circulation therethrough, means be-V ingprovide'd for permitting the dropping ofthe ball to the lowermost branch of the coil `after the samekhas been moved with the waterto the topmost branch of the coil.

' A [still further object ofthe invention is to provide a novel method and apparatus for preventing the collection of foreign matter' on the inner surfaces of Water heaters of the above ucharacter, which will be durable and efficientin use, onek that will be simple kand easy :to manufacture and one which can be incorporated with any type of `water heater.

.y y"With these and other objects in view, the

invention consists inthe novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in t-he accompanying drawings, in which` drawings: A 'Figure 1l shows the application of my improvedjdevice to a water heater commonly used in stoves and furnaces, Figure '2 isa plan View of a coil which can be successfullyus'ed .in such type of water heaters, and I 1 n Figure 3 isa diagrammatic View showing the application of my device to water heaters using a source of -extraneous heat such as gas, oil, electric'heaters.` Y f Y lRjeferring'to the drawings in detail, where` in similar reference characters designate cor-v responding .partsk throughout the severaly views, the'letter A generally indicates the lire pot jof a conventional furnace or range with a water coil or loop B arranged therein. As usual in such t' pes of heaters al stand boiler of the desire capacity G is arranged adjacent'to one side of the furnace or range having extending into the upper end thereof the'source of cold water supply indicated rno outlet of the coil, thefcold water pipe being of a less diameter than the coil, of a ball formed of non-corrodible material and of a slightly less diameter than the diameter ofthe coil arranged therein to travel with the circulation of water through the coil' lcoil having upper and lower legs and a bend connecting the legs at one end, of a curvilinear couplingconnecting the otherjends of the legs and having oppositely located ymeans for the connection of water inlet and outlet pipes thereto, the coupling being interiorly of greater diameter than the legs, and a substantially spherical cleaning element freely movable in the'circuitcomprising the legs, the connecting bend, and the coupling and of a diameter slightly less than the interior diameter of the said legs and bend.

4. The combination with a water heating coil having upper and lower legs and a bend connecting the legs at one end, the other ends of the legs being both located in the same vertical plane, ofa curvilinear coupling connecting` the last mentioned ends of the legs and vertically disposed and having means at its upper side for the connection of a water outlet pipe and means at its lower side for the connection of a water inlet pipe, the coupling being interiorly of greater diame-l ter than the legs, and a substantially spheri- 'cal cleaning element freely movable in the circuit comprising the legs, the connecting the said legs and bend.
